NAME
ispcvt — verify if current video driver is pcvt driver
SYNOPSIS
ispcvt [−c] [−d device] [−n] [−v]
DESCRIPTION
The ispcvt utility allows the user to check whether the current video driver compiled into the kernel is a pcvt driver. The major and minor release numbers of the driver are also checked. Furthermore ispcvt is also able to print out the values of all the ’’PCVT_XXXXXX’’ compile time options, the driver in the current running kernel was compiled with.
The options are as follows:
−d
Specifies a device for which the check is done.
−v
Specifies being verbose. On success the name and revision is reported, on failure which comparison failed.
−n
print the number of compiled-in virtual terminals.
−c
This options prints out the values of all ’’PCVT_XXXXXX’’ #defines which were given to the compiler at the time the currently running kernel was compiled. Specifying −v with the −c option gives a verbose listing of the compile-time options.
DIAGNOSTICS
The ispcvt utility exits with one of the following values:
0
driver is pcvt and major and minor numbers match
1
open(2) or ioctl(2) system call failed
2
driver name mismatch
3
name matched, release major number mismatch
4
name and major number matched, release minor number mismatch
5
usage error
